Definitions
- This invention relates to rack structures, e.g. for containing telecommunications equipment, and in particular to equipment racks provided with resistance to earthquake induced forces.
- the object of the invention is to minimise or to overcome this disadvantage.
- an equipment rack for supporting communications equipment including a generally rectangular base member, first and second side members extending from opposite sides of the base member in a direction perpendicular to the plane of the base member, a top member coupling the free ends of the side members, and means for securing the base member to a support surface, wherein the securing means is adapted to prestress the base member so as to transfer force from the base member to the side members whereby to raise the vibrational response of the rack to a value at which earthquake induced vibration of the rack is inhibited.
- an earthquake resistant structure including a generally rectangular base frame member, first and second elongate side members extending from opposite sides of the base member in a direction perpendicular to the plane of the base member, a generally rectangular top member coupling the free ends of the side members, and means for securing the base member to a support surface, wherein the securing means is adapted to prestress and distort the base member so as to transfer force from the base member to the side members whereby to raise the vibrational response of the structure to a value at which earthquake induced vibration of the structure is inhibited.
- a method of mounting an equipment rack for supporting communications equipment on a support surface including a generally rectangular base member, first and second side members extending from opposite sides of the base member in a direction perpendicular to the plane of the base member, a top member coupling the free ends of the side members, and means for securing the base member to the support surface, wherein the method includes prestressing the base member via the securing means so as to transfer force from the base member to the side members whereby to raise the vibrational response of the rack to a value at which earthquake induced vibration of the rack is inhibited.
- the securing means comprises a number of mounting bolts which are over-tightened or over-torqued so as to distort the base and to generate the required level of prestressing of the structure.
- the torque required to effect the required degree of prestressing may be determined from simulation vibrational measurements on a sample rack, and this setting can then applied to all installed racks of that design.
- the rack may contain e.g.. optical transmission equipment which is used to carry voice and data in bulk between remote points such as telephone exchanges or other telecommunications entities that require reliable high bit rate data connectivity.
- optical transmission equipment which is used to carry voice and data in bulk between remote points such as telephone exchanges or other telecommunications entities that require reliable high bit rate data connectivity.
- FIGS. 1a and 1b are respective left hand and right hand general views of the earthquake resistant equipment rack
- FIG. 2 is an exploded view of the rack of FIGS. 1a and 1b showing the construction thereof;
- FIG. 2a is an enlarged view of the base frame assembly of the rack structure of FIGS. 1a, 1b and 2;
- FIG. 3 is a more detailed view of the base structure of the rack of FIGS. 1a, 1b, and 2 and illustrates the forces generated when the rack is mounted on a support surface;
- FIGS. 4a and 4b are longitudinal and transverse sectional views respectively of the base frame of the rack of FIGS. 1 to 3 and illustrate the effects of prestressing and distortion of the base frame introduced by mounting the rack on a support surface.
- the rack which is constructed from steel sheet or plate comprises a generally rectangular base frame structure generally depicted as 11 to which side members 12 and 13 are secured e.g. by welding.
- the free ends of the side members 12 and 13 are coupled by a top frame 14 to form an elongate box-like frame structure.
- a rear cover plate 15 is secured to the side members.
- the side members 12 and 13 are folded to provide additional stiffness and to provide longitudinal cabling channels. Further stiffening of the assembly is provided by side stiffener members 121, 131 and 122,132, and by rear stiffener members 123, 133.
- Cabling brackets 124, 134 may be mounted on the respective side stiffener members 121,131 to retain cables (not shown) disposed in the cabling channels provided in the side members 12 and 13.
- the cabling channels in the side members may closed by side covers 136 (FIG. 1a). In the view of FIG. 1b the right hand side cover has been removed to expose the cable channel.
- the joints between the side members 12, 13 and the base assembly may be covered by respective L-shaped cover plates 125, 135.
- the base frame (FIG. 2a) is constructed as a welded structure from sheet steel which has been folded to provide a generally rectangular cross sectioned tube and is braced by first and second transverse members 111a, 111b, and by a cross member 16 disposed between the transverse members. Further bracing or stiffening of the base frame is provided by base stiffener members 112, 113 attached to the front and rear respectively of the base frame and a longitudinal member 114 disposed between the transverse members. A kick plate 115 may also be attached to the front surface of the base frame.
- First and second anchor plates 17 formed from steel plate are disposed on the base frame whereby the rack may be secured to a support surface.
- the anchor plates are provided each with slotted openings 171 for receiving bolts 172 for engaging corresponding threaded mounts (not shown) provided in the support surface.
- Foot bracket members 18 provide a mounting for the base frame structure 11 on the support surface.
- Further openings 174 are provided in each anchor plate 17 in register with corresponding openings 115 in the respective transverse member 111a, 111b, for receiving screw threaded adjustment feet (not shown) which may be used for mounting the rack on an uneven surface.
- the anchor plates may be replaced by bar members which perform an equivalent function.
- the rack top frame 14 (FIG. 2) is of similar construction to that of the base frame and comprises a generally rectangular structure which is braced by transverse members 141 and by front and rear stiffeners 142 and 143 respectively.
- first and second bracket members 144 secured to the top frame may be used to secure the top of the rack to an overhead support (not shown).
- the rack can support telecommunications equipment disposed on circuit boards or cards which can be secured to the rack in the normal manner.
- This equipment may form part of a conventional wired or optical communications system, or it may form part of a mobile or a fixed access cellular communications system.
- the rack assembly is in use secured to a substantially horizontal mounting surface via anchor bolts 172 which are located in the slotted openings 171 in the anchor plates 17 these openings being disposed inboard of the base frame periphery.
- the bolts engage corresponding threaded mounts (not shown) provided at appropriate positions in the mounting surface, the slotted openings providing a degree of leeway or tolerance in the positioning of the threaded mounts.
- the anchor bolts 172 are fully tightened to secure the base frame structure 11 in abutment with the mounting surface and are then further tightened so as to prestress the base frame by providing a slight distortion thereof. As shown in FIG. 3, this provides a downward force against the base structure and a corresponding reaction force on the base structure from the support surface.
- FIGS. 4a and 4b show respectively longitudinal and transverse cross-sections of the base of the rack.
- the anchor bolts 172 are further tightened, the anchor plates 17 are strained and the inner portions of the base frame structure are compressed relative to the outer portions so that the upper surface of the base frame structure assumes a dished or concave configuration.
- the magnitude of the distortion is small and is within the elastic limit of the base material and of the anchor plates. Typically this distortion is less than 1 mm. For explanatory purposes the distortion has been shown exaggerated in FIGS. 4a and 4b.
- the distortion of the base resulting from the over tightening of the anchor bolts is illustrated schematically by the curves A--A and A'-A' in FIGS. 4a and 4b respectively.
- the forces imparted to the base structure via the support surface cause the base structure to distort between its normal dished concave configuration and a concave configuration of smaller radius of curvature, i.e. a more dished configuration, so as to absorb some of the received vibrational energy.
- This distortion is illustrated schematically by the curves B--B and B'-B' in FIGS. 4a and 4b respectively.
- This prestressing and consequent slight distortion of the base structure transfers part of the prestressing force to the side members of the rack so as to introduce a slight bending of the side members, i.e. so as to cause a slight inward bowing of the side members.
- This introduction of strain into the side members improves the resistance of the rack to low frequency vibrations resulting from a seismic shock. These vibrations have a broad frequency spectrum, but it is generally accepted that it is the low frequency vibrations that cause maximum damage.
- the accepted industry standard described in the Bellcore NEBS documentation requires that, to provide adequate resistance to Zone 4 earthquake conditions, the rack should not respond to frequencies below 6 Hz. This document also specifies suitable wave forms for application to the structure on test.
- a sample of the rack to be tested is mounted on a horizontal platform which is subjected to vibrations of various frequencies and the response of the rack to those applied vibrations is determined.
- the upper portion of the rack is loaded with a mass of 100 pounds to represent the maximum quantity of equipment which the rack will hold when in service.
- This test is detailed in the Bellcore NEBS document referred to above. We have found that by providing an appropriate degree of prestress of the base structure, the minimum frequency to which the rack responds can be raised to at least 6 Hz and typically to about 9 Hz, i.e. well above the frequencies at which significant damage can occur.
- the precise degree of over tightening of the anchor bolts to distort the anchor bars and base frame to provide the desired prestressing will depend on the base construction and the total area or footprint of the base member and can be determined by experiment by tightening the anchor bolts to various torque settings and subjecting the rack to the Bellcore earthquake simulation test. In this way an optimum torque setting can be determined for a particular rack construction, and this torque setting is then applied to all similar racks when these are installed.
